Newton`s 2nd Law in Cartesian and Polar Coordinates
... 1.7 Two-Dimensional Polar Coordinates Although Newton’s 2nd law takes a simple form in Cartesian coordinates, there are many circumstances where the symmetry of the problem lends itself to other coordinates. To illustrate this, let’s take a look at 2-d polar coordinates. You should already have s ...

... Momentum is a conserved quantity in physics. This means that if you have several objects in a system, perhaps interacting with each other, but not being influenced by forces from outside of the system, then the total momentum of the system does not change over time. However, the separate momenta of ...
